Big Brother has confirmed that the first live task will consist of a tug-of-war game and will result in the housemates receiving a surprise reward.
According to Channel 4 the reward will reveal a Big Brother's twist
This morning the housemates awoke to discover that markings had been placed on the ground in the garden but they won't receive an explanation until this evening.
At the beginning of the show, the group will be asked to elect a leader who will choose two teams and one housemate will be called into the diary room to be issued with a sealed envelope, which will reveal their instructions.
The result of their challenge will be announced live during the Channel 4 show at 9.05pm
